The adorable and enigmatic axolotl is capable of regenerating many different body parts, including limbs, organs, and even portions of its brain. Scientists hope that a deeper understanding of these extraordinary abilities could help make this kind of tissue regeneration possible for humans. With news today of the first complete axolotl genome, researchers can now finally get down to the business of unraveling these mysteries.

Axolotls are tiny aquatic salamanders whose only native habitat is a lake near Mexico City. Many animals, such as frogs, sea stars, and flatworms, are capable of tissue regeneration, but the axolotl is unique in that it can regenerate many different body parts over the course of its entire life cycle, including limbs, tail, heart, lungs, eyes, spinal cord, and up to half of its brain.
